Its been on-again-off-again over the past decade or so for Cleveland hip-hop group Bone Thugs-n-Harmony. The Grammy-winning act earned a huge following in the 1990s with a blend of melodic singing and hyper-speed rapping. But internal strife and a prison sentence eventually left fans wondering what the future held. Answer: Reunion shows, of course. All five members Layzie Bone, Flesh-n-Bone, Bizzy Bone, Krayzie Bone and Wish Bone will grace the Revolution Center stage for this 20-year-anniversary gig, which includes a tribute to the late, great Eazy-E.
